question 71

Multiple Choice

You have collected the data for a Time-Cost CPM Scheduling model analysis.The time is in days and the project "direct costs" are given below. $\begin{array}{|l|l|l|l|l|l|}\hline & \text { Immediate } & \text { Normal } & \text { Crash } & \text { Normal } & \text { Crash } \\\hline \text { Activity } & \text { Immediate } & \text { Time } & \text { Time } & \text { Cost (Direct) } & \text { Cost (Direct) } \\\hline \text { A } & \text { None } & 3 & 2 & \$ 300 & \$ 400 \\\hline \text { B } & \text { A } & 3 & 3 & \$ 100 & \$ 100 \\\hline \text { C } & \text { A } & 1 & 1 & \$ 200 & \$ 200 \\\hline \text { D } & \text { B and C } & 3 & 2 & \$ 400 & \$ 550 \\\hline \text { E } & \text { D } & 2 & 1 & \$ 500 & \$ 900 \\\hline \text { F } & \text { E } & 3 & 3 & \$ 200 & \$ 200 \\\hline \text { G } & \text { F } & 2 & 2 & \$ 100 & \$ 100 \\\hline\end{array}$
The indirect costs for the project are determined on a daily duration basis.If the project lasts 16 days the total indirect costs are $400,15 days they will be $250,14 days they will be $200 and 13 days they will be $100.At what day do we achieve the lowest total project cost (i.e. ,direct plus indirect costs) ?

• A)16 days
• B)15 days
• C)14 days
• D)13 days
• E)12 days
